请问一下楼主，我的邮件系统也是按照您的文档来搭建的，每天接收和发送的邮件加起来大概有一万多封，我查看图形日志邮件队列图的参数如下：
active  total:1842msgs  avg:1.07msgs/min max:11msgs/min
hold    total:0msgs  avg:0msgs/min max:0msgs/min
deferred  total:65593msgs  avg:36.79msgs/min max:40msgs/min
Incoming  total:2779msgs  avg:1.6msgs/min max:6msgs/min
请问怎样才可以提高邮件系统的性能，另外请问此邮件系统的并发量是多少，default_process_limit一般设多大合适？

1万来个email属于比较低的流量，默认的设置应该能比较好的运行了。如果用户没有反应邮件收发缓慢的话，一般不需要做什么调整。

为了安全起见，我把ldap、extmail、extman、authldaprc配置文件里的密码都设经过crypt加密的就不行，而使用明文密码就没问题。请问一下是不是不能设成加密密码？

什么意思？将密码crypt？？是将数据库的密码加密后写到webmail.cf，webman.cf里？

是的，我先用slappasswd -h {crypt}命令生成加密密钥{CRYPT}MRiJNbObnzVlA，然后把SYS_LDAP_PASS = secret改成SYS_LDAP_PASS = {CRYPT}MRiJNbObnzVlA

很多同事经常反应外面发过来的邮件好多接收不到，用163的邮箱就可以收，我的邮件系统日志大部分报错和下面差不多，请问一下老大是什么原因？
Jan 14 08:26:24 mail postfix/smtpd[26849]: NOQUEUE: reject: RCPT from unknown[192.168.1.2]: 504 <57CC8D40FB8A4F5>: Helo command rejected: need fully-qualified hostname; from=<v9huang2009@yahoo.com.cn> to=<likanggui@foresee.com.cn> proto=ESMTP helo=<57CC8D40FB8A4F5>

为啥牛人这么多?

谢谢了，赶紧去看看，学习学习！！

问题在这里：

引用:

zero uid or gid not permitted

您检查1下uid/gid的有关配置，估计是字段写错了。

谢谢楼上的回答，问题已经解决，新的问题是，我在extman操作新加用户的时候，log出现很多类似的错误
bdb_equality_candidates: (active) index_param failed (18)
bdb_equality_candidates: (mail) index_param failed (18)
bdb_equality_candidates: (virtualDomain) index_param failed (18)
但是我用ldap工具看到生成的资料都正常

我现在发邮件给自己的话会出现 unknow user，这是怎么回事呢？

这些错误暂时还不清楚具体是怎么产生的，您看看ldap的工具里有没有可以修复index的？

另外，发给自己user unknow，估计是您的投递部分没有设置好，导致找不到用户记录吧？
